To make the skull look lighter I had to draw either bounce animation or additional frame to slow it down, but I just had no time at all to do that. Instead I added those scattering particles and I was satisfied by how it looked.

The skull is filled with darkness; maybe there is a black hole inside it. I think it isn't a huge mistake to leave it as it is.

The weight is one of the things i like most about this piece. Like the skull is the only real solid bit cos it stays intact when the body crumbles to nothing. Anyways this is very nicely done. I find it strange a grim reaper is full of rainbows and butterflies but that just adds to it's unique charm here.
